Bringing you pain-free connectivity while you travel. As travelers ourselves, we’ve faced the painful situations of not finding Wi-Fi, losing the SIM card you’ve carefully taped to the back of your phone, and the horror of coming home to an unexpected roaming bill. We believe that in today’s modern world, connectivity and freedom should be accessible to all. Airalo is here to take away the pain and stress of researching and seeking out the best roaming deal. We’re here to let everyone stay connected globally while keeping it simple and pain-free.

For most, travel begins by picking a place on a map. But what if we followed our passions instead? Where would they take us? Thermal’s mission is to change the way we travel for the better, by putting passions first. For many of us, activities like surfing, fishing, skiing, cycling, cooking, and yoga are more than just hobbies to pass the time — they’re a core part of who we are. Our passions connect us to community, cement friendships, and make us feel alive. They inspire us to test ourselves, to leave home and explore the world. Traveling in pursuit of our passions brings us experiences we remember for life. Whether it’s the annual group surf trip with lifelong friends, or a solo journey to score a bucket-list wave on the other side of the world, we live for these adventures. Unfortunately, finding and planning these trips is often fraught with difficulty and stress. It’s our goal to change this. Thermal is building the marketplace for passion-driven travel. With a founding team that has shaped companies like Kayak, Airbnb, Hotwire, OpenTable, and Apple, we have the skillset to build a world-class company. Its early days, but were working relentlessly to bring our vision to life, and we’re excited to meet like-minded individuals eager to join us on our journey.
